The purpose of this study is to gather basic data on dietitian's general characteristics, working conditions, job achievement and job satisfaction. Thereby, a formulation can be worked out to improve dietitian's job achievement and satisfaction. The study was conducted during one week period, spanning July 23 to July 30, 1998. The method of the study was to distribute 560 questionnaires to the primary school dieticians working in the city of Tae Jun, located in Choong-Cheong Province. Out of 560 questionnaires that was distributed, 327 were returned. Moreover, 318 out of 327 questionnaires that was returned was valid enough to be processed by the SAS Program. About sixty percent of the respondents(61.1%) indicated that they were between 26 to 30 years old. Moreover, approximately half of the respondents(48.8%) were unmarried. In terms of the level of education, the bachelor's degree was reported as the most common education level(56.3%), while 3.8% of the participants reported achieving graduate degrees. The number of years in working in the profession ranged from 2 to 5 years. Furthermore, approximately 74% of the respondents indicated that, on average, they earned over ￦800,000 per month. In terms of the type of the school setting, 52.8% of the respondents worked in the urban setting, whereas, 60.0% worked in the rural school setting. Of these schools, about thirty eight percent(38.7%) of the schools were relatively small sized schools(400 students or less ). In terms of dietitian's sense of job satisfaction, the areas that showed relatively high level of satisfaction was in the menu control work(3.90) and purchase control work(3.90). However, appallingly low job satisfaction was indicated in the areas of personnel management (2.96%), and nutritional education and counsel(2.73%). Furthermore, job satisfaction varied greatly depending on age, wage, type of the food service, and type of school. The highest satisfaction was indicated in the areas of supervisory position(3.42), work itself(3.31%), co-workers(3.11). Other facets that led to job satisfaction were periodic wage increase(2.19%) and promotion opportunities(2.79%). In conclusion dietitian's job achievement showed significant correlation with job satisfaction. The study suggests that, in order to improve the overall job satisfaction of the dieticians, it is necessary to improve the working conditions of dieticians in primary schools. Secondly, there is a necessity for improving the status of the dieticians by raising the salary and treating the dieticians with the same level of respect in comparison with teachers or executive officials. Finally, another way of raising the job satisfaction of the dieticians is to provide opportunity for continuing education. So that, they can further their career in their chosen field.

North Korean leader Kim Jong Un decided to open 19 Economic Development Zones which are located in all over the country, as a new economic development strategy. The strategy is estimated for accepting change from socialistic planning economic system into socialistic market economic system gradually. South Korean government is busy preparing for reunification between South and North Korea. Recently, many forums and seminars for the issue, 'reunification' are held by public side as well as private sector. This study is focused on making practical strategy for developing 13 Economic Development Zones which were established in 2013 in concurrence with South and North Korea. The study assessed investment potential of the 13 zones in terms of locational, economic and legal competency from the investor's perspective of south koreans. 5 E.D.Zs, Songrim, Hyungdong, Heungnam, Chungjin, Waudo were chosen to be developed on the preferential basis. Development cooperation between South and North Korea on the 13 E.D.Zs will increase the income of north koreans in rural areas by creating jobs, contribute to boost North Korea's economic growth, and bring forward economic integration between South and North Korea.

This study was performed to determine the levels of quality of life(QOL) according to the grade of long-term care service in the elderly people who were judged from long-term care insurance, and to reveal its association with related variables. The interviews were made to 958 elderlies in urban and rural areas from March 1 to May 31, 2009. The mean scores of QOL among all subjects were $55.4{\pm}15.62$(Grade I; $49.7{\pm}14.17$, Grade II; $56.8{\pm}14.62$, Grade III; $59.4{\pm}16.36$), and they were lower according to the higher grade of long-term care insurance. The multiple regression analysis was used to reveal the explanatory powers of factors influencing on the level QOL. Such factors as educational level, monthly income, subjective health status, depression and MMSE-K were shown to affect their QOL in Grade I, Grade II, and Grade III with explanatory powers of 45~62%.

Improved estimates of populations at risk for quick and effective response to natural and man-made disasters require spatial disaggregation of zonal population data because of the spatial mismatch problem in areal units between census and impact zones. This paper implements a dasymetric surface model to facilitate spatial disaggregation of the population of a census block group into populations associated with each constituent pixel and evaluates the performance of the surface-based spatial disaggregation model visually and statistically. The surface-based spatial disaggregation model employed geographic information systems (GIS) to enable dasymetric interpolation to be guided by satellite-derived land use and land cover data as additional information about the geographic distributor of population. In the spatial disaggregation, percent cover based empirical sampling and areal weighting techniques were used to objectively determine dasymetric weights for each grid cell. The dasymetric population surface for the Atlanta metropolitan area was generated by the surface-based spatial disaggregation model. The accuracy of the dasymetric population surface was tested on census counts using the root mean square error (RMSE) and an adjusted RMSE. The errors related to each census track and block group were also visualized by percent error maps. Results indicate that the dasymetric population surface provides high-precision estimates of populations as well as the detailed spatial distribution of population within census block groups. The results also demonstrate that the population surface largely tends to overestimate or underestimate population for both the rural and forested and the urban core areas.

According to the local highway tunnel ventilation guideline, ventilation capacity calculation should be performed at the speed ranging from 10 km/h to 80 km/h. This is so reasonable method considering uncongested and congested traffic conditions in urban tunnels. But recently due to low traffic volume and very low congestion frequency in rural highway tunnels, it seems to be an inadequate way to apply the guideline. Therefore the calculation should be performed separately for the free flow and congested traffic cases classified by the appropriate decision model. This paper aims at determining unnecessary running speed range for reasonable tunnel ventilation design, considering free flow and congested traffic conditions. Firstly, traffic volumes in highway tunnels were collected and if any, the causes of congestion were investigated. And with concept of 'margin speed'($u-u_m$), the decision model on traffic congestion was developed. Applicability of the decision model was also analyzed with case study. According to the results, when design speed is 100 km/h, with V/C less than 0.1, then the range of unnecessary speed in tunnel ventilation design is less than 40 km/h; for $V/C{\leqq}0.35$, $V/C{\leqq}0.6$ and $V/C{\leqq}0.75$, the unnecessary speed ranges are found to be ${\leqq}30$, ${\leqq}20$ and ${\leqq}10km/h$, respectively.

This paper suggests how Korean housemaids, called Sikmo, and Korean-Chinese migrant domestic workers have similar class positions and therefore form a dual identity in their interactions with female employers. rough spoken stories of the experiences of 27 females from Seoul, including Korean-Chinese domestic workers, Korean housemaids, and their employers, this research effectively overcomes the dichotomous discourse of natives versus foreigners. Instead it suggests the new interpretation that it is not foreignness but class inferiority of the domestic workers that plays a key role in establishing relationships with employers. Korean housemaids and Korean-Chinese domestic workers, both groups of whom are migrant workers, have developed coping strategies to enhance their labor value by spatially relocating themselves from their home society to a new society. They possess a similar labor status in women's history, being of low income, low education, and rural births. Consequently, these women experience 'translocal anchoring,' meaning their identities are intertwined with that of their home societies, and employers perceive them based on the characteristics of these places. The Korean employers perceive that the domestic workers' morality and intellectuality are inferior based on their class differences. This stigmatizing process leads employers to regard domestic workers as ambivalent people, not only threatening outsiders but also objects of pity, needing love and protection of their employers. The employers educate them culturally, teaching them skills to survive in the urban environment. These skills include cooking and language, in addition to advice on long-term plans to blend into society.

In order to establish the watershed water quality management strategy of Total Maximum Daily Load(TMDL), it is necessary to understand the relationship between water quality component impacts, and to identify the impacts on downstream target point of watershed water quality management of waste treatment plant(WTP) discharge and upstream/tributary loads. In this study, we determined the impacts between the water quality contaminants, and traced water pollution sources using monitoring data of ministry of environment in tributaries and main stream and WTP monitoring data. Test area is set to Geumho river basin which has characteristics of urban and rural area and composes of GeumhoA, GeumhoB, GeumhoC watershed units in TMDL. The clustering with five grades of discharge data and the correlation analysis were performed through the FDC(Flow duration curve) analysis, which more clearly identified the points and water contaminants deteriorating target water quality of downstream point. This can be used as a tool for tracing pollutants with FDC analysis, and will help us establish the watershed water quality management strategy for TMDL target point in watershed more effectively.

Microalgae are a diverse group of photosynthetic organisms and abundant in every ecosystem in the biosphere. They are common in aqueous environments including marine, brackish and fresh waters and in some habitats that lack eukaryotic life such as some hot springs and highly alkaline lakes. Microalgal biotechnology that is focused on the microalgae-based production of a variety of useful materials such as pharmaceutical comfounds, health foods, natural pigments, and biofuels is considered as an important discipline with the development of biotechnology. In addition, the mass cultivation of microalgae can also contribute to improving the environmental quality by reducing the concentration of $CO_2$ which is one of major gases lead to global warming. Consequently, it seems that the microalgae can be used as an efficient, renewable, environmentally friendly source of high-value biomaterials such as chemicals, pigments, energy, etc. and the microalgal biotechnology will most likely represent a larger portion of modern biotechnology.

The purpose of the present study was to examine daily lives of elderly welfare recipients and their experiences with social welfare services. Researchers collected and analyzed data through individual interviews with 11 elderly welfare recipients. A major theme in the time context was "Daily lives enduring physical and mental sufferings alone and mismatches of social welfare services": 'Starting same tedious days: trading diligent work for basic living assistance', 'Forced ritual of having meals', 'Struggle with depressing night: not attentive welfare services at closing hours', 'Welfare services suspended in holidays', 'Mind and body withered by economic hardship in winter', 'Social support for enduring weary lives'. In the space context, a major themes was "Inadequate welfare services and social interaction in the context of social isolation": 'Unhygienic and unsafe living environment', 'Hiding places: spending tedious days in vacant lots', 'Community welfare centers useful only for healthy elderly', 'Differences and similarities of elderly in urban and rural areas', 'Receiving restricted medical services at hospitals', 'Hard-to-reach public institutions', 'ambivalence about living as welfare recipients'. Based on the findings, the researchers proposed implications for policy and practice to improve elderly welfare recipients' quality of life.

The Correlations Between the Labour Market Structure and Poverty of the Regions The main objectives of this study are to make an investigation into the spatial characteristics of poverty and to analyze the effects of regional labour market structure. Most previous studies on poverty were more likely to examine internal factors like the characteristics of poor households or family structures than external factors in terms of the regional environments. In order to achieve these goals, this study used the Small Area Estimation designed to estimate the income of each household and then calculate the poverty rate of each local area in order to examine the spatial characteristics of poverty. The poverty distribution in Korea showed the local labour market structures effect on the region poverty rate. The Korean economy now exhibits a big gap between the haves and the have-nots and between urban areas and rural areas. The poverty rate of particular regions will increase and those in the areas will face deteriorated circumstances falling into poverty traps. This study reflects this stern reality and empirically proved the strong need for consideration of regional characteristics in conducting studies on poverty and related policy amendments.
